Hi, I want to capture video from PAL cemera (4:2:2 format) by V4L2,and resize the video to 4:2:0 CIF format,there are two questions: 1,How to de-interlace two field as one frame and convert it to be CIF frame? I saw the "EncodeDecode" demo, which de-interlace directly with V4L2_FIELD_INTERLACED option.yet it doesn't resize the frame and convert 4:2:2 to 4:2:0. 2,Then I want to try the DM6446 "resizer" driver to conver. It seems that i have to read frame by V4L2 into mmaped DDR, and then using "resizer" to convert this frame buffer into a new output buffer. BUT The document "TMS320DM644x DMSoC Video Processing Front End (VPFE) User's Guide" said that there is a Video port interface (10−bit RAW) between CCDC and resizer,which means data should be transfered directly into resizer? Can anyone tell me how to use V4L2 and resizer driver to do that? _______________________________________________ Davinci-linux-open-source mailing list Davinci-linux-open-source@linux.davincidsp.com http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
